Development and application of a new power analysis system for testing of geothermal thermoelectric generators

This article presents a new thermoelectric generator power analysis system (TEG-PAS) for the examination of all parameters of the thermoelectric generators (TEGs) operated by geothermal or any liquid heat. As a sample application, the developed TEG-PAS has been tried on a TEG of 100 W. During electrical energy generation, the values of the electrical, the thermo-electrical and the thermal variables of the TEG have been transmitted to the TEG-PAS by the employed sensors. Thus, the using of several devices simultaneously has been eliminated while the power performance analyses are being carried out.
